China markets dip as real-time foreign trading data withheld

The change, announced by three major bourses in mid-April, is aimed at reducing market volatility. But the removal of immediate information on the buying, selling and total turnover of A-shares in Shenzhen and Shanghai by foreign investors has stirred concern over data transparency.
